Re: Schema.org

There is more on RDF/a, in particular

http://schema.org/docs/datamodel.html

"Mapping to RDFa 1.1
Our use of Microdata maps easily into RDFa 1.1. In fact, all of
Schema.org can be used with the RDFa 1.1 syntax as is. The RDFa 1.1
version of the markup looks almost isomorphic to the Microdata
version. Given below is an sample RDFa 1.1 markup, of the example
given for the Product type."
